To all wit-omit may cancer-m j Be it known that I, Mosns F. CARR, a citizen' of the United States, fo'rmerlyresiding at Newton. in the county of ll liddlesemstate of Massachusetts, and now a resident of Lexington, in the county of Middlesex, State of'l .:lassachusetts, havednvented an Improvement in Separable Fasteners, of which the following description, in connection with the accompanying drawings, is aspeci fication, like characters on the drawings representing like parts.

This invention pertains to improvements in separable fasteners. It is among the ob jects of theinvention to'provide a separable fastener of the three-side lock type wherein stud and socket are separable by relative tipping movement in a predetermined direction only, and in which the number of parts will be reduced to a minimum and the construction simplified.

In the drawings, which'show a preferred form of my invention selected for illustrative purposes j Y i Figure I is a front elevation. of the fastener secured to its carrying fabric;

Fig. 2 is a section on the line 22 of Fig. 1, being partly in elevation;

Fig. 3 is a section on the line 3-3 of Fig. 2, being partly in elevation; and

Fig. 4 is'a rear elevation of the socket.

Referring to the drawings and to the preferred form of my invention selected for illustrative purposes. I have shown a fastener including a stud having a head 4, a neck 5, a shank portion 6. the shoulder between the head 4 and'neck 5 sloping somewhat. l have shown a socketincluding a casing 7 se cured to the socket-carrying fabric 8 by prongs 9 penetrating said fabric and clinched overa back plate 10 on the opposite side of the fabric from the socket cas- 'ing. The back plate 1.0 is provided with a stud-receiving aperture elongated to permit relative tipping movement of stud and' socket in the directions indicated by the arrows in Fig. 2. In the casing 71' have shown a transverse stud-engaging jaw 20, which may be and preferably is, as shown, a part of the spring 21.. The socket casing 7 provides above the stud opposite the yielding jaw 20 a fixed or rigid jaw 22. The spring is held in the casing and the yielding jaw is guided by projections bent over from the marginal portions of the socketcasing, such projections being preferably of the general character indicated at 23, 24, so as to permit relatively free guided movement ofthe yielding 20. W hen the studis entered the solid jaw '22,'tlius "holding the Theginclination of the shoulder between the head of thelstud parts in engagement.

and its neck is preferably such that no ordinary strain would produce such a resolution of forces as to permit the stud to be separatedfrom the socket. Relativetipping movement of stud and socket in. three] directions is prevented by the" sides and bottom, of the elongated'aperture in the back lat 9, whil such relative tipping movement U the 'fourth direction ispermittedby reason of the elongation of the aperture in the back plate ,above the stud. I The projection :22

provides arelatively large bearingsurface of the fixedjaw'22 against the neck offthe stud and terminatesin a proper position to act as a stop precluding excessive upward movement of the yielding jaw.

WVhile I have shown and'described a preferred form of one embodiment of my invention, it will be understood that major changes involving omission, substitution.

alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of I my invention, which is following claims.

Claims? best defined in j the A separable fastenerjcomprising. in"

combination, a stud having a head and a neck presenting a shoulder between them. and a socket havmg a spring-containing casing, said casing apertured to permit passage of the head of the stud therethrough and presenting above the stud an unyielding neck-engaging jaw, aresilient jaw opposing said unyielding jaw, said yielding jaw formed by a terminalportion of said spring, andspring-retaining portions 24 thrown inwardlyfrom the periphery of said casing to support said yielding jaw.

2. A -.separa-bleffastener comprising, in

5. A socket for three-side lock fasteners including a spring, a casing, and a back plate, said spring providing yielding jaw atteindant release of the socket from the stu r 6. A socket for three-side lock fasteners including three piecesa. casing,-a spring presenting resilient jaw means and a back plate said casing containing said spring and presenting an integral projection guiding and supporting said resilient aw means and said back plate located on, the opposite side of the socket carrying fabric from said casing and spring, while providing a stud receiving aperturethe sides of which limit tipping movement of the studin the socket in three-directions while providing acliearance permitting substantial tipping move ment in a fourth direction.
